Summary
o A vulnerability in the web-based management interface of Cisco Virtualized
Voice Browser could allow an unauthenticated, remote attacker to conduct a
cross-site scripting (XSS) attack against a user of the interface.
This vulnerability exists because the web-based management interface does
not properly validate user-supplied input. An attacker could exploit this
vulnerability by persuading a user of an affected interface to click a
crafted link. A successful exploit could allow the attacker to execute
arbitrary script code in the context of the affected interface or access
sensitive, browser-based information.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
